摘要： PURPOSE:To enable the lighting of a part intended to inspected flaws alone at a high intensity of illumination, by a method wherein ultraviolet rays condensed into a small section are transmitted with a condenser mirror through an optical fiber and scattered light from an end of the fiber is reflected with a cap mirror to irradiate in a specified direction. CONSTITUTION:Current is supplied to a mercury lamp 1 from a proper power source such as rectifier to emit ultraviolet rays. The ultraviolet rays thus emitted are condensed with as condenser mirror to one end 4a of a flexible optical fiber 4 to be transmitted with the optical fiber 4 after a visible light component is suppressed with a glass filter 2 and reaches the other end 4b thereof near an inspector section to irradiate a surface 6 to be inspected. Except for traveling forward, light caused as scattered light at the other end 4b of the optical fiber is reflected forward with a cap mirror 5, thereby achieving a higher brightness along with limited light range.

摘要： PURPOSE:To minimize the power consumption of a magnetizing/demagnetizing apparatus, by a method wherein the apparatus for mounting and feeding a part to be inspected on a Y-shaped yoke apparatus for magnetizing and demagnetizing the part to be inspected is entirely constituted of non-magnetic parts. CONSTITUTION:A part to be inspected is supplied to a turntable 5 at a first stop position thereof in a constant posture from a parts feeder 6 through a chute 7 and mounted to one of the apparatuses 4 mounting the article to be inspected of the table 5 in a correct posture by a reversal apparatus 8. Next, at a second position of the table 5, the part to be inspected is transferred to the center position of a magnetizing/demagnetizing apparatus 9 and excited by the alternating magnetic field generated by the coil of said apparatus 9 through the table 5 and a rotary magnetic field is induced to magnetize the part to be inspected. At this position, a definite amount of a fluorescent magnetic powder is applied to the part to be inspected. The part to be inspected is separated from the apparatus 9 in a demagnetizing direction at the beginning of the next rotation of the table 5 and, at this time, said part is demagnetized and, in the rotation stop apparatus of said table 5, the fluorescence of the magnetic powder is detected in a dark room 10 by a fluorescence magnetic powder detection apparatus 13 having an optical fiber 11 and a photomultiplier 12 to perform flaw detection. At the next stop position, good and inferior products are classified according to the flaw detection result.

CONSTITUTION:In a working installation of a taper rod, a reduction roll 20 and a holding roll 21 are provided to a tension roll device to reduce a wire size. The roll 21 is fixed to a machine frame 25 through bearings, and the roll 20 is set freely slidably in the vertical direction with respect to the frame 25 through bearings 23. That is, when a reduction body 33 is vertically moved by extending and contracting a press driving body 32, the reduction roll 20 is vertically moved by a link member 42 consisting of the 1st lever 37 and the 2nd lever 40. Further, the reduction body 33 is arranged on the extension of a vertical plane of reduction roll 20. Furthermore, the roll 20 is connected to a driving device through an universal coupling 29.
